The design of beer or soda bottles
Of course that every person is familiar with the design of beer or soda bottles, but have you ever wondered why they have that impressive neck? It seems that this design was created specifically to keep the temperature of the drink intact when you hold it in your hand.
This way, your body temperature will not heat the drink and you will be able to refresh yourself with a cold beer. Sound great, right? Well, imagine drinking a cold and fresh beer on a summer day, but how about a warm one?
